HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed May 2, 1906. Serial No. 314,825.

T 0 all whom it may concern:

The operation is as follows: The liquid hy- Be it known that I, EMANUELE MOLINARI, drocarbon or hydrocarbon derivative flows subject of the King of Italy, residing at from the cistern A through feedpipesM to the Genoa, Italy, have invented new and useful Hydrocarbon-Burners, of which the following is a specification.

My invention relates to apparatus for burning hydrocarbons and their derivatives and especially contemplates the provision of an apparatus wherein the heat given off by the burning oil vaporizes the liquid hydrocarbon as it passes from the cistern to the burner.

The detail construction will appear in the course of the following description in which reference is had to the accompanying draw ing, forming a part of this specification, like numerals designating like parts throughout the several views, wherein Figure 1 is a side elevation of a hydrocarbon burner constructed in accordance with my invention, and Fig. 2 is a plan view thereof.

In the practical embodiment of my invention, I employ a metallic casing, formed with the floor-section H and the integral upper casting G, surmounted by a tank or cistern A from which the liquid hydrocarbon or hydrocarbon derivative to be consumed flows through a plurality of feed pipes M to an inclined surface B upon said casting G, which surface is at first precipitous and steep, but after a short descent bends so as to form a long inclined platform I down which the liquid fuel slowly flows. This inclined surface D is pierced to form a plurality of ports or openings (1 and long parallel slots E alined and spaced from each other a distance.

corresponding to that between the feed-pipes M are cut in the inclined platform I, and through a port or opening C in the casting G connection is made with a powerful blower or like air-current su )ply so that an air-current passes through & into the interior F of the burner from which it issues through the s aced openings (Z in the part B and the para lel slots E in the angular platform.

inclined surface B, which surface being heated by the flame of the burner partly vaporizes the descending oil. The portion of the oil not vaporized continues to flow down the angular platform until struck by the current of air issuing through the ports (Z and the parallel slots E, which nebulizes the same and blows it into the [lame of the burner where it is consumed together with the hydrocarbon vapor from the part B. The flame may come in contact with a row of firebricks L at the to of the burner, the incandescence of which would greatly assist in vaporizing the oil.

It is evident, the surface of the burner must befirst heated by burning the nebulized oil before the vaporization will take place and that the higher the temperature of said surface and the fire brick the .more complete will be the vaporization.

Having described my invention, I claim:

In a hydrocarbon burner, the combination with a cistern adapted to contain liquid fuel, of, a metallic casing provided with a port for the admission of air therein, said casing having its upper surface formed with a relatively steep inclined portion and a relatively slight inclined portion, said casing being further provided with a plurality of air-discharge alined openings at the juncture of the relatively steep and slight inclined portions and with a plurality of spaced air-discharge slots extending thcrethrough longitudinally of said relatively slight inclined portion and at substantially right angles to said air-discharge openings.

In testimony whereof I have allixed my signature in presence of two witnesses.
